Ivanka Trump's Daughter Arabella and Son Joseph Are Getting So Big—See the Pic!

On Thursday, the 32-year-old entrepreneur Instagrammed a picture of her 7-month-old son Joseph and her 2-year-old daughter Arabella cuddling, and it's easy to see how much bigger mommy's "sweet babies" have gotten in just a short amount of time!

Arabella has a full head of thick, pretty hair, and her kid brother's locks are filling in quite nicely, too. The siblings hold each other's hands in the snap, and as baby Joseph uses his free hand to hold his own bottle, big sis Arabella cradles a toy doll in hers.

Clearly, Arabella is a fan of her baby brother, and it seems that the tot's mom and dad Jared Kushner set her up to be a great big sister from the beginning. "We had Arabella with us when we found out the sex of the new baby and, after, we bought her a baby doll of the same gender," Ivanka told Fit Pregnancy last year. "I think she understands what's coming, but then she throws me periodically by rubbing her own belly and saying, 'My baby sibling!' So, I don't know if she fully gets the biological elements of what's going to transpire, but she knows something is about to change. "

Donald Trump's daughter admitted she even found motherhood to be "a lot more chaotic than I could have imagined," but she's adapted. As she explained it, "You have to become much more flexible and malleable in your thinking and in the ways you get things done."

And it looks like Ivanka and her hubby are doing everything right to raise two happy, healthy kids.
